ANlMAL-POKE.

SPECIFICATION forming part of Letters Patent No. 241,602, dated May 17, 18 81.

Application filed October 27, 1880. (No model.) i

To all whom it may concern by declare the following to be afull, clear, and exact description of the invention,such as will enable others skilled in the art towhich it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in animal-pokes, the object being to produce an article of this character which shall be of light weight and simple construction, durable and safe in use, and of easy adjustment, and one that may be manufactured andsupplied to the trade at a comparatively light cost.

With these ends in view, my invention consists, first, in the combination, with an inner and outer bow, of guide-rods connecting the bows, springs encircling the guide-rods, and spurs rigidly secured to the outer bow and arganged to pass through apertures in the inner My invention further consists in the combination, with an inner and outer how, each provided with a cross-bar, and guide-rods connecting the bows, of springs encircling the guiderods and spurs rigidly secured to the outer bow and its cross-bar, said spurs adapted'to pass through the inner bow and the cross-bar, thereof.

My invention further consists in the combination, with an inner and outer bow, each provided with a cross-bar, and guide-rods connectingthe said bows, of springs encircling the guide-rods, spurs rigidly secured to the outer bow and its cross-bar and arranged to pass through apertures in the inner bow and its cross-bar, said outer bow being provided with hooks respectively at its upper and lower portions.

My invention further consists in certain details of construction and combinations of parts, as will hereinafter be described, and pointed out in the claims. I

In the accompanying drawings, Figure 1 is a view in perspective of my improved animalpoke. Fig. 2 is a detached view of the outer bow. Fig. 3 is a detached view of the inner Be it known that I, DWIGHT BRINTNALL, of. Dysart, in the county of Tania and State of Iowa, have invented certain new and useful Im- I provements in Animal-Pokes and I do here-- how; and Figs. 4 and 5 respectively represent, in detached view, the'cross-bars of the outer and inner bows of my improvement.

Let A represent the outer bow, and B' the cross-bar thereof; G, the inner door, and D the cross-bar thereof andletE representthe guiderods, F the spurs, Ghooks, all of the said parts being elements in my improved poke. The bows A and 0, similar in shape to those used in yokes, are formed of any suitable material but I prefer to use wood for reason of its light ness and cheapness. The open end of each bow is joined by cross-bars B and D, which are provided at both ends with a metallic band, a, forming the loops b, into which the ends of the bows are received and retained by means of wires or bolts 1). While this method of attachment is shown in the drawings, it is evident that there are many other ways of attachment which might be resorted to, and with equally good results.

To the under side of the inner bow, C, any desired number of guide-rods, E, are attached, which latter pass freely through apertures 0 formed in the outer bow, A, the free end of the said guide-rods being provided with a head, (I, a washer or nut sufficing to hold the two bows together. Spiral springs H, encircling the guide-rods, operate to retain the bows apart and shield the animal to which the poke is attached from the sharp spurs F, which latter are secured to the outer bow, A, and have their pointed ends sheathed in apertures c in the inner how, 0. In the normal relative position of the two bows to each other these spurs are kept out of sight and annoyance; but as soon as any pressure of suflicientforce to overcome the resiliency of the springs His brought to bear upon either of the bows, by direct contact therewith or through the mediumship of the hooks G, the spurs will be pressed through the apertures and enter the flesh of the animal wearing the poke until the pressure or force is discontinued. The hooks G attached to the upper extremity and lower ends of the outer bow are designed to engage with a fence or anyother obstacle that the fractions animal may encounter.

An animal-poke constructed as described Ice in the foregoing description is light, cheap, durable, and when attached to a breachy animal will prevent its jumping over, crawling through, or breaking down fences.

I would have it understood that I do not limit myself to the exact construction shown and described, but hold myself at liberty to make such slight changes and alterations as come within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is g 1. In an animal-poke, the combination, with an inner and outer bow, each provided with a cross-bar, of guide-rods connecting the bows, springs encircling the guide-rods, and spurs, rigidly secured to the outer bow and arranged to pass through apertures in the inner bow, substantially as set forth.

2. In an animal-poke, the combination, with an inner and outer bow, each provided with a cross-bar and guide-rods connecting the bows,

of springs encircling the guide-rods and spurs rigidly secured tothe outer bow and its cross- 25 bar, said spurs adapted to pass through apertures in the inner bow and the cross-bar thereof, substantially as set forth.

3. In an animal-poke, the combination, with an inner and outer bow, each provided with a 0' cross-bar and guide-rods connecting the. said bows, of springs encircling the guide-rods, spurs rigidly secured to the outer bow and its cross bar and arranged to pass through apertures in the inner bow and its cross-bar, said 3 5 outer bow being provided with hooks respectively at its upper and lower portions, substantia-lly as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of 40 October, 1880.

DWIGHT BRINTNALL.
